VAPOEIZER.

Application filed January 22, 1924. Serial No. 687,718.

To @ZZ whom t may concern.'

Be it known that I, EUGENE KRAFT, a citizen ot the United States, residing at Spokane, in the county of Spokane and State of lVashington, have invented new and useful Improvements in Vaporizers, oil which the following is a specilication.

The object of this invention is to provide means for more completely vaporizing the explosive mixture in the combustion chainber ot' an explosion engine and also vaporizing any lubricating oil that may be pumped into the chamber by defective action of the engine pistons.

A further object is to provide means tor vaporizing the explosive mixture prior to the first explosion to facilitate starting of the engine.

A further obj ect is to attach the structure of this invention to the usual skeleton gasket which is interposed between the bloc-k and head of the engine so that the application ot the device of this invention may be made to any engine without altering or drilling either the head or block.

Other features and objects of this invention will be more fully described in connection with the accompanying drawing and will be more particularly pointed out in and by the appended claims.

In the drawing F ig. 1, is a plan view of the engine head looking down onto the usual skeleton gasket to which the structure of my invention is shown attached.

Fig. 2, is a sectional view on line 2 2 of Figure 1.

Fig. 3, is a sectional view on liuc 3"-53 of' Figure 1.

Fig. 4, is an enlarged sectional view on line 4*-4: of Fig. 5, showing how the strip is insulated from the gasket and the engine.

Fig. 5, is a plan view thereof.

Like characters of reference designate similar parts throughout the diiierent tigures of the drawing.

As illustrated, 1 designates theblock of the engine which is provided with intake valves 2 and exhaust valves 3. The head is designated at l and the usual interposed gasket at 5. There is provided the usual combustion chambers G to which the valves 2 and 3 open, the said valves being at one side of the cylinder bores 7. I have shown spark plugs S, extending downwardly through the head 4, the terminals 9 thereot heilig in relatively close superposed relation to thc intake. valves 2. It will be understood that this is merely a conventional showing or one type oi engine merely sutlicient to illustrate one application of the device of my invention thereto.

`Next referring to one part of the means for vaporzing the mixture, and its other functions, 10 designates what may be a continuous 4metal strip, or a strip made up of sections, and which extends lengthwise of the engine and across the path of flow of the mixture passing' from the intake valves 2, into the combustion chambers 6. This strip 10, which I have shown to be continuous, extends across portions 11, of the skeleton gasket 5, and is preferably although not essentially, attached thereto, and in any event, it rests upon the gasket. There are many advantages in actually attaching this strip to the gasket, and I consider this a novel ieature of my invention so to do. As shown in Figs. t and 5, the gasket 5 is preterably grooved and in the bottom of the groove a sheet of electrical insulation 12 slightly wider than strip 10. A like insulating sheet 13, isV disposed on top of said strip. Fasteners let, secure the strip and insulation to the gasket but do not pass through strip 10, and hence the latter is electrically insulated from the engine and is movable into and out of place together with the gasket 5, and can be sold in commerce with the latter. Ahreast of the valves 2, I preferably impart a turn to a short section of the strip, as indicated at 15, so that a flat face, instead of an edge, is presented toward the mixture flowing trom the intake valve 2. i

This strip is shown included in a circuit having a limb 16 connected with one end of the strip and connected with a source of current supply 1'?, which may be the battery oit the car. The other limb of the circuit is indicated at 18, the strip 10, forming a resistance. This may be arranged so that a switch may be employed to be closed before starting the car to heat the strip and thus heat the air and vapor in all the combustion chambers 7, with a view of Vaporizing the mixture so that the engine may be readily started. After the first effective explosion or explosions, this circuit may be opened, and then the strip will be highly heated by combustion in chambers 7, and this heated strip will not only serve to more completely vaporizeall the mixture, but Will, in addition, vaporize any oil that may be pumped into the engine by detectively Working pistons. AThus, by insuring vaporization of oil, carbon deposits on the valve lseats Will be prevented and hence the maxi-` mum compression retained.

i consi'der'iny invention complete and op.-

Verativeas thus tar described, but have found that great advantages flow from the additions of certain other features which IA VWill next describe in detail. Y i y only lie4 closeto the terminals V9, but which also are disposed in an elevated area ivith respect to the intake valves so that Whatever incoming mixture that was not vaporized by the stripsi10,'ivould be acted upon by strips 16. consider Ait a feature ot' this invention todispose portions ot' the heating or Vvaporizing strips 16 in close proximity to, and specifically in surround` ing Vrelation with terminals 9, `and in the specific torni shown, i `provide an opening 19, in each strip ,16, and with this arrangement, lain able to subject 4theterniinals to a most etl-i'iective action o'heat topreven fouling of the terminals.

It will be understood that these strips 10 and 16 will be of 'very thin steelV or any material ot' such a .character that iviil be quickly heated to a high temperature. Thus, in those areas betiveen the wallsot the combustion "chamber, and adjacent the valves, therewill be'highly heated elements for eificiently vaporizing not only the explosive mixture, but also any lubricating oil thatY may have Ybeen pumped into these chambers. y i

lrconside'r it ateature of novelty to pertoi'ate portions 15, as indicated at 15 so that they will also act breakers to break up the mixture. v

it is believed that my inventionwvill' be clearly 4understood trom the foregoing, and i; do not wish to be limited thereto except for such limitations as the claims may import. 'Y Y 1. In combination, an explosion engine having a combustion chamber 'and intake and exhaust valves opening` to said chain-Y bcr, ignition terminals above the intakeA valve, a primary metal vaporizing strip cxtending adJacent said valves tor vaporiziiig the mixture and oil while the engine is running, means forheating said strip prior to the first explosion to vaporize the inixture and a secondary inetal strip. extending abreast said valves and in close proximity to said terminals and adapted to be heated by combustion to preventiouling of said terminals'` and also to assist in vaporizing the mixture. i Y Y 2. In combination, an explosionV engine having a combustion Chamber and intake and exhaust valves' opening thereto, said engine being divided into a block and head,

va skeleton 0'asket interposed between said block and head, a fiat strip ot metal having itseiids fastened to and electrically insulated from, said gasket and engine and adapted to be heated by combustion after the first explosionsto vaporize the mixture and oil, and means for electricallyheating said strip prior to the first explosion to vaporize the 'mixture 'ot the intake valve being turned up to present a Hat face toward the mixture/flowing from said valve, and said turned up' portion beingperforated to act asa breaker.

4. in combination, an explosion engine divided into a head and block and liavinga Y gasket therebetween, said Yengine having an explosion chamber and an intake valve opening thereto and ignition terminals in said cli-amber abovel said'valve, and an arcuate vaporizing strip having its ends securedy to said gasket vand its intermediate portion extendingV upwardly abreast of and being slotted to permit projection thereinto of said terminals. l

5. In combination, an explosion engine divided into a head and block and having a gasliet therebetween, said engine having'an explosion chamber and an intake vvalve opening thereto and ignition terminals in said chamber above said valve, and an arcuate vaporizing strip having its ends secured to said gasket and its intermediate portion exanimals.,
